What does it mean when different physicians disagree about a diagnosis? I am joined by Dr. Shani Herzig as we explore this issue in the second part of my series on the development of diagnosis. We’re going to discuss the advent of signal detection theory in the middle of the 20th century as new diagnostics such as laboratory testing and x-rays started to challenge the classical view of diagnosis. Along the way, we’re going to talk about focal infection theory and why it seems that everyone in older generations had their tonsils removed as children, early and very inefficient chest x-rays, British radar operators trying to figure out if they were looking at a flock of geese or a German bomber, and finally probably one of the most important people in medical diagnostics that you’ve never heard of -- Jacob Yerushalmy.   If you want to purchase any Bedside Rounds swag, the store is at  https://www.teepublic.com/stores/bedsiderounds.

Bedside Rounds is a storytelling podcast about medical history and medicine’s intersections with society and culture.  Host Adam Rodman seeks to tell a few of these weird, wonderful, and intensely human stories that have made modern medicine.

What does it mean when a computer can make better medical decisions than a human? The progress in large language models, and in particular the popularity of ChatGPT, has brought these questions to the forefront in 2023, but we’ve been discussing this for over 50 years. In this episode, Dr. Shani Herzig and I are going all the way back to the early 1970s with the invention of AAPHELP, the first real clinical decision support system, and the first time doctors had to contemplate working with – or competing against – computer systems.

What happens when a patient far from surgical care – say, at the bottom of the Pacific ocean on a submarine, or at a research base in Antarctica in the middle of the winter – develops a surgical abdomen? This dilemma was the impetus to build the first truly effective clinical decision support system – and to grapple with what it means when a computer can make better medical decisions than a doctor. In this episode, part one of three, we discuss the dramatic stories of appendectomies at Novolazarevskaya and aboard the submarine Seadragon. Also, there’s a brand new #AdamAnswers about the origin of the word “scut.”

American doctors spend the majority of their time during the day on the computer, either writing or reading notes about their patients; only a small fraction is spent with the human beings in their care. Technology itself – especially the electronic medical record – has often been blamed for this. But in this episode – a recorded grand rounds that I gave at the San Francisco VA in 2022 – I argue that this alienation has its roots in the way we’ve decided to organize clinical data, and the assumptions that we’ve made about the nature of medical care. In particular, I’m going to discuss one of the most influential medical thinkers of the second half of the 20th century, Larry Weed, his invention of the problem-oriented medical record and the SOAP note, and how his insight – that medical documentation fundamentally influences how we think about our patients – changed the way we think about our patients.

In the past episode, cultural and medical historians Lakshmi Krishnan and Mike Neuss discussed the history of the actual work of the doctor – Holmesian detective, data entry clerk, or something else altogether. In this episode, we conclude our discussion by talking about what type of metaphors are best suited for clinical work. Plus a brand new #AdamAnswers about the reason that American doctors are so obsessed with using, well, the # symbol in our notes.

71 - A Doctor's Work, part 2

What do doctors actually do? Are they Sherlockian detectives, hunting down obscure clues to solve intractable cases? Are they virtuosic experts, training for half a lifetime to bring the latest science to bear to cure disease? Or are they clerks, whose main job is to collect and enter data into the electronic health record? In this episode, Adam is joined by medical and cultural historians Lakshmi Krishnan and Mike Neuss to discuss the stories we tell about our own work – and how this often conflicts with the realities of clinical practice.
